2. Description of the Related Art With the recent increase in the size of retail stores and the invasion of urban suburbs that are inconvenient to transport, large-scale retail stores are now equipped with large-scale parking lots for the convenience of users. It was In this parking lot, the parking lot utilization rate becomes high during the days and hours when shoppers are concentrated, and at that time, it becomes difficult to find an empty parking space in the large parking lot. For this reason, the user wanders around the parking lot in search of an empty space, which is very dangerous.

As a countermeasure for this, a large number of guards can be appropriately arranged in the parking lot to guide the passengers to an empty space, but in a large-scale facility, the labor and cost for this are enormous. .

On the other hand, as a method that does not require a large number of guards, a vehicle sensor electrically connected by a cable is arranged in each parking space, and whether there is an empty space or not based on the information from this sensor. Part of the method is to monitor the location and place in the control room. However, laying a cable in an existing parking lot requires temporary suspension of use and large-scale construction, and once the cable is buried, the layout of the parking lot cannot be changed easily. .

[0005]

The problem to be solved by the present invention is that the parking lot can be installed without interrupting the use of the existing parking lot, and the parking lot user can be accurately guided to an empty parking space. It is to provide a parking lot management device capable of

[0006]

In order to solve the above-mentioned problems, the parking lot management device of the present invention detects the presence or absence of a vehicle in each parking space in the parking lot and wirelessly transmits this detection signal. And a parking space display means for displaying an empty parking space in the parking lot to the user based on a detection signal from the vehicle detection means.

Here, as the parking space display means, a display panel provided in the parking lot can be used, or a ticket issuing machine having a printer function for printing an empty parking space on the parking lot use ticket can be used.

Further, as a power source of the vehicle detecting means, a solar cell and a battery storing the solar cell can be preferably used.

[0009]

In the parking lot management device of the present invention, the vehicle detection signal can be transmitted cordlessly to the parking space display means, so that the vehicle detection means can be placed at an appropriate position even in the existing parking lot that has already been used. Just install
A management system can be easily constructed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual diagram of a parking lot management apparatus according to an embodiment of the present invention. Reference numeral 1 is a sensor unit as vehicle detection means for detecting the presence or absence of a vehicle in a parking space and wirelessly transmitting this detection signal. So, it will be installed in the parking space. Two
Reference numerals 3 and 3 denote a receiving unit and a display panel, respectively, which constitute parking space display means for displaying to the user an empty parking space in the parking lot based on a detection signal from the sensor unit 1.

One sensor unit 1 is provided as a parking space 4
The number of vehicles can be sensed, and the detection signal of the parked vehicle from the sensor unit 1 is received by the receiving unit 2 installed in the parking lot. The receiving unit 2 identifies which sensor unit is the originating signal from the receiving timing or receiving frequency of the signal or the code number unique to each sensor unit added to the receiving signal, and stores it in the memory built in the receiving unit 2. Know the available parking space in the parking lot by comparing it with the accumulated received data. Then, the information is displayed on the display panel 3 provided in the parking lot. In this embodiment, one sensor unit 1 monitors four units. However, depending on the arrangement method and the structure of the sensor unit 1, one unit may be used as one unit. The number of vehicles that can be managed by the unit is not particularly limited.

FIG. 2 is a detailed view of the sensor unit 1.
a is a solar cell panel as a power source, 1b is a storage battery for storing surplus power, 1c is a sensor for detecting the presence or absence of a vehicle, 1
Reference numeral d is a radio wave transmission / reception unit, and 1e is an antenna.

In the present embodiment, an ultrasonic sensor is used as the sensor 1c for detecting the presence / absence of a vehicle, but of course the invention is not limited to this, and an infrared sensor or the like can also be used. The transmission / reception unit 1d can suitably use a system such as a specific low power radio in consideration of the conditions and environment of the managed parking lot. Further, when the sensor unit 1 does not need to receive the timing signal and the confirmation signal returned from the receiving unit 2, only the transmitting function may be used.

The display panel 3 is a display panel system having an illustration of a parking lot layout and a display function corresponding to each parking space, and LEDs, light bulbs, mechanical display color switching, etc. are used. The display panel 3 is appropriately arranged near the entrance of the parking lot or a key place in the parking lot, and can visually notify the user of the empty parking space.

As described above, since the display panel 3 and the sensor unit 1 arranged in each parking space are wirelessly connected to each other, the sensor unit 1 can be placed at an appropriate position even in an existing parking lot that has already been used. You can easily build a management system just by installing it. Further, the solar cell panel 1a of the sensor unit 1 has a power supply capacity more than that required to drive the sensor unit 1 in fine weather, and an excessive amount is accumulated in a storage battery in the unit to supply power at night or in bad weather. And
